Cable TV 4k. What is the new format

The material discusses the possibilities technical parameters, differences and price of a 4K (UltraHD) receiver for Tricolor.

A receiver with 4K support allows you to watch movies, TV series, entertainment and documentaries in high quality when the picture and sound are difficult to distinguish from reality. The image on the screen combines the depth of colors and clarity of lines. But such benefits can be felt if an appropriate TV is installed.

Do Tricolor subscribers need GS a230 or not?

The question of many subscribers after the appearance of this receiver model is whether to buy an “advanced” set-top box or not. After all, the number of channels in 4K format is not so large.

Those who like to watch broadcast content in high quality and want to immerse themselves in the atmosphere of a TV show are recommended to choose this set-top box. Moreover, if there is suitable TV. The receiver will allow you to expand your options when watching important and favorite programs - interrupting, resuming the show, recording a movie you liked or a program that you couldn’t watch on time. And also the user can use the device for mirroring on multiple devices.

If the subscriber does not have a TV with UltraHD support that can reproduce images in high quality, purchasing a receiver will not bring joy and satisfaction.

Sales of 4K TVs are growing as new companies enter the market and cheap models. Is there any sense in budget TV? Yes. But you can’t do it without helpers.

And the lower price threshold for video systems (!), which will not need to be changed tomorrow, does not start with the numbers that advertising tells us about.

The real benefits of 4K

UltraHD, or 4K, really makes the difference. No matter what anyone says, but with a normal TV, such a resolution on screens larger than 40 inches justifies itself in our small apartments. A high-quality film is distinguished by its bright colors, pleasant color transitions, precision and smooth movements. Is this not enough?

Then you can move closer and play one of the most modern games. Dust and shadows are more lifelike in 4K than before.

But the coolest thing is high-quality digitization analog recordings. Like alive. This is where even parents stop grumbling: “The Irony of Fate used to be livelier than it is now.” After all, in general, they are right. And only 4K helps to cope with the effect of “colorized cinema”.


And with a 4K display, you can buy TVs of absolutely incredible sizes. The thing is that on a 65-75-inch screen the corresponding video file looks like FullHD. This means that from a distance of a couple of meters - no squares.

Next time I will buy a panel that is at least 70 inches. And I advise you.

Although there are other advantages. Let's go in order.

Formats and resolution: what 4K do we need?

Ultra-high-quality videos could revolutionize the world of home entertainment centers. But even major developers still cannot agree on a common space for new formats.

Technically, 4K refers to any graphics or video file with a horizontal resolution of approximately 4,000 pixels. But some have their own opinion: for example, cheap LG TVs use RGBW matrices, where the actual resolution is 2880x2160 instead of 3840x2160.


ATTENTION: A 4K TV must have an “UltraHD” sticker. This is a generally accepted standard that prohibits such tricks. But it does not guarantee success either.

A device that complies with the standard must reproduce content with a resolution of 3840 × 2160 and a frame rate of 24 to 120. But 24-30 frames do not provide sufficient smoothness in fast-moving scenes. You need at least 60 fps.


But behind a high-quality picture there is one more factor: the quality of the file being viewed. And it, in turn, depends on the format, codec with which the video was encoded. And the bitrate set at the time the file was created.

Low bitrate means no transitions, flat ragged shadows, artifacts. The TV must be able to play files with a bitrate above 60 Mbit/s and streaming video, encoded with the VP9 codec (YouTube and all, all, all). Otherwise you will need an attachment.

Fact: Apple TV 4K can't play VP9 - no YouTube in 4K.

Colors and ranges: no need to buy obviously outdated ones

Last year, high color gamut (aka HDR) seemed like a fairy tale. But the improved colors were quickly appreciated by users and producers (Amazon and Netflix not only produce new films, but also digitize old films). Therefore no HDR support new TV risks becoming obsolete in a couple of years - especially for games.

We must not forget about color display. Any matrix (or projector lamp/laser) reproduces standard 8-bit color. Sufficient for HD content. But in 4K large diagonal This image appears dim: too much of the screen remains black. Gray transitions on 8 bits are invisible.


And this applies to all natural color gradations. For a high-quality image, you need 10-bit color - like in professional monitors for designers’ work. Requires HDR10 support. So far there are few such recordings, but this format is becoming the main one thanks to the active distribution of Apple and Sony recordings.

By the way, look at the file in HDR10 It won’t work on a primitive TV - the colors will be incorrect and artifacts will appear. The conversion will take a long time. Either buy a TV with HDR support to grow, or stop at FullHD.

What does it take for a TV to become UltraHD?

A good matrix and formal support for 4K does not mean that you can watch movies in the appropriate resolution on your TV. Suitable data transfer interfaces are needed.


To dual band Wifi is better not be carried out. In apartment buildings and 5 GHz is occupied. And to watch streaming 4K video you need a stable channel with “clean” speed 100 Mbit/s and higher. “Clean” - after taking into account losses. This means that the router and provider must provide almost 250-300 Mbit/s to the server.

A fashionable remote control can always be replaced with a Buetooth keyboard - it is more convenient. But you need the notorious Bluetooth or support (a protocol that allows external devices to work).

By the way, USB 2.0 allows viewing only “light” files. If necessary direct connection- necessary USB 3.0, and the ports must support both the speed and power supply of the standard. So it’s better not to count on them.

What can't you do without? In order:

• HDMI 2.0(1.4a does not work with HDR);
• Ethernet(better than Wi-Fi);
• support for working with network drives(DLNA and home computer, or a file server can replace any service);
• Miracast or AirPlay(depending on the platform - it’s just useful, it’s convenient);
• optical output on speaker systems(often this is easier than purchasing a receiver to implement multi-channel audio).

No 4K without a media server

But you can get away with analog/digital television decoders. Of course, several 4K channels in Russian are consistently broadcast in packages from well-known providers satellite television. But online cinemas and YouTube turn out to be perhaps the most popular way to obtain content.


On the other side, Netflix HDR And Amazon 4K not relevant in Russia (without spoken English). IN OKKO And “Amediateke” not much 4K. Most 4K HDR movies in iTunes Store - but each one needs to be bought. Not every TV, especially in the lower price segment, knows how to work with all the necessary services.

Therefore, without multimedia player(especially if there is a network file server) can't be avoided. I connected the Android box - and no problems with support for codecs, formats, fast conversion files. Actually, there are few options - either these (as an option - Shield), or Apple TV box 4K. Or only the content that the TV manufacturer has allowed. Then you need to choose a model for Android TV.


Fact: WebOS, OperaOS, tvOS still limit the user. And to watch 4K, you can't rely on just one streaming service or website.

If you want to watch old movies, buy an expensive TV

Old films were shot either analogue or digital cameras. With analog everything is clear - we digitize, retouch frame by frame, connect and watch (tedious and expensive). But it initially contains more data than early digital records.

With “digital” it’s generally more difficult. Increase resolution digital file in HD and it’s impossible - the quality will not increase due to manipulation.


Some manufacturers equip TVs with a software increase in resolution - “upscaling”. Don't confuse upscaling with simple stretching. The first one tries to fill in the missing ones based on the colors of neighboring pixels. The second one does nothing - large squares of the same color remain.

Example from life: I have 2 TVs that support UltraHD: LG with upscaling and Hisence without it. Old films can only be watched on the first one.


So far, old films are being transferred to 4K very reluctantly (only

Being one of the largest satellite television companies in Russia, Tricolor never ceases to improve to the delight of its customers. Today, three TV channels are open for broadcasting. highest definition, which are available to all users subscribed to the “Unified” package. Tricolor offers a new 4K Ultra HD format that four times better Broadcasting format in FullHD: the image is clearer, brighter, almost with the effect of presence.

What is the new format

New additional package consists of three TV channels with maximum image realism. No advertising, only the best masterpieces of foreign and Russian cinema, exciting documentaries and educational programs, as well as the mysterious and captivating world of fashion. You will feel like spectators in the hall, and not in front of a TV screen, thanks to the ultra format. The package includes three TV channels:

1. "Tricolor Ultra HD" immerses viewers in the exciting world of cinema, there is absolutely everything - melodrama, science fiction, comedy and even horror. The ultra-clear picture will make you experience all the events along with the characters.
2. INSIGHT UHD will make you feel like an explorer and pioneer. It will show you all the secrets of living nature and even awaken your thirst for science. The channel is completely educational.
3. "Fashion One" is an excellent world of fashion and the brightest stars of the secular world. He will show you how to dress correctly and beautifully, and talk about the lives of models, singers and actors.

Incredible HDimage clarity will create a feeling of complete presence, no matter which of the three TV channels you watch.

The new package is only available to those who have a special module and a TV designed for 4K Ultra HD. Other users will not notice the image quality.

What do you need to watch the channel?

A regular receiver from Tricolor TV is not capable of receiving and transmitting the new HD format. It can be configured for a package of these channels, but their main essence will not be available to you. Also, not every TV supports new technologies and recognizes such a clear picture.

To be able to fully immerse yourself in HD broadcasting, you will need a TV screen with a built-in digital tuner satellite type. As a rule, these are models from forty-eight inch screen UHD 4K Flat Smart TV HU8500 Series 8. These include eight models from LG and five from Samsung. All of them have a built-in module and Ultra HD resolution of at least 3840x2160.

Besides suitable equipment, you need to be a registered user of the Tricolor television company, subscribed to the “Unified” package, and deposit subscription fee in the amount of 1200 rubles per year. If you are not a client of this television company, but want to gain access to the package, then all that remains is to switch to a new provider.

Television in ultra HD format on site Russian Federation Today only the Tricolor company broadcasts.

How to connect a package

Already now, anyone can set up their equipment to broadcast new TV channels. The main thing is to make sure that you have a TV with support for 4K Ultra HD and a screen resolution of 3840x2160 and higher, as well as a Cl+ module registered with Tricolor TV and a smart card with the “Unified” package. If everything is in place, you can start setting up.

Television.

But it arises logical question What should I have extra to watch 4K or UltraHD TV?

It is clear that first, you need to acquire a 4K TV, and then the equipment that will deliver this 4K to your TV.

The main thing you need to know is that the device must support the HEVC (H. 265) and DVB-S2 compression standard.

For example, we insert into the TV a CI+ CAM module with an NTV+ access card or a set-top box like this: Beelink i68

And so the TV set-top box Beelink i68.

With a not very powerful processor, consisting of eight Cortex-A53 cores with a frequency of up to 1.5 GHz, there is a PowerVR G6110 GPU with support for decoding video formats H.264 and H.265 in resolutions up to 4K inclusive.

In the Beelink i68 media player, the new Rockchip SoC works in conjunction with 2 GB RAM.

The volume of the built-in eMMC module is 8 GB, there is a slot for microSD cards up to 64 GB. Built-in dual band wifi adapter 802.11 b/g/n and Bluetooth 4.0, there is a Fast Ethernet port.

TV connects to HDMI port 2.0, for peripherals there are three USB 2.0 connectors, microUSB and an S/PDIF output.
Beelink prefix i68 runs Android 5.1 OS with KODI multimedia shell.

The dimensions of the product are 12 x 12 x 2.4 cm.

For owners of Sony UHD TVs (last year's release).

The latest firmware update allows the Sony X9, X85 and S9 to receive UHD TV channels using built-in satellite or cable tuners.

This is very good news, because these TVs still cannot receive UHD channels, but they are gradually appearing in some countries or are starting to work in test mode.

After replacing the firmware, you will need to activate 4K TV reception in the settings:
Home => Settings = Digital> Video Mode => 4K

What are the trends for the future?

The first UltraHD TV channels will appear on offer digital platforms by the end of 2015, after which their number on the market will begin to increase.

Spread channels of this format will be primarily through satellite broadcasting, which has wider technical capabilities compared to terrestrial TV or IPTV technologies.

Last but not least, it is noted that the sale of 4K channels for end user will be more profitable.

The main factor “FOR” is the interest of manufacturers in selling equipment to the end consumer, who often strives for “fashion” and purchases this or that item even when he does not really need it or for prestige.

But for now we have 4K Tricolor TV which is registered on 12169R as Infochannel " Tricolor Full HD". (12169 R, DVB-S2, 8PSK, SR 27500, FEC 3/4, Tricolor TV tests - Infochannel Tricolor Full HD 4K)

Many people are talking about their intention to launch a TV channel in 4K format in the foreseeable future. And it seems that UltraHD transmissions will become commonplace in the near future.

As I wrote above, it is enough to have a 4K TV that supports the HEVC/H.265 encoding standard with a DVB-S2 tuner, and if you also want to watch encoded channels, you need a CI+ module.

Take my word for it, the impression is simply amazing, as if you are looking into open window, the picture is colorful and clear.

As for the 4K Tricolor channel, I use it in the LG 55UB820V Ultra HD with the CI+ module and watch it. Tricolor constantly plays several videos on this 4K channel, for example, the Victory Parade.

We look forward to the start of commercial broadcasting in this format. While 4K videos from YouTube are helping out, which I watch using Smart Hub TV.

However, 4K is still tomorrow for many, and FUL HD is today and channels in given permission keep appearing.
But I note that on a 4K TV and FUL HD it looks much better, there are more pixels.

Good luck, Friends!
